The frequency counter is simply the Weeder counter slightly modified for my application. Horsehockey!! It was never intended to replace the relatively ancient 8038 any more than a Corvette was expected to replace a VW Beetle. However, if a higher voltage AC supply is used, the regulators will most probably require a heatsink for any sort of continuous operation. Setting the Frequency Setpoint (fs) via the user interface invoces the WFG software to set the signals If, Vf and Cf through the control of four DAC channels DAC[0 – 3] and selecting the timming capacitors needed to achieve the fsetpoint .
